While arithmetic circuits using 2’s complement representation are easy to implement, it is well-known that the sign-extension bits of a 2’s complement number cause high switching activity in digital arithmetic circuits. Such switching is undesirable in low power applications. In this work, we exploit the sign-extension property of a 2’s complement number and propose a reduced representation of 2’s complement numbers to avoid sign-extension. Instead of having the high switching activity at the… CONTINUE READING
